This is a common scam and is a variant of the Advance Fee Scam (also known as the 419 scam).
It is most commonly carried out by Nigerians or strangely by people from elsewhere but claiming to from Nigeria.
There is a story, sometimes pages of it, trying to explain how the sender is some kind of bank official or government official and they have control of bank accounts. One of which belongs to a recently deceased person with no next of kin and no official will. Here’s the con. The sender wants you to pretend to be the next of kin to the dead person and claim the inheritance, which you then split with the sender.
An example of this scam is an email from Mr. Konibally Kone, although he spells his name differently at places in the email so must be confused on who he is today.
His deceased client supposedly left $13.7 million which he and I can share as long as I follow his instructions.
He also promises it is totally safe as he has all the required legal documents.
Of course, he does not have an official email address – just a Gmail personal address in the name christpoher 654321.
All I have to do is reply with name, address, contact details, date of birth and Id document.
For anyone who does reply, the scam follows the standard pattern where he or she gets drawn into the scam and has to pay an unexpected but small amount for some purpose then another fee then another and so on till the victim realised there is no fortune, just a scammer taking their money.
Also, the scammers will likely sell your details to other criminals who carry out identity theft.
Money for nothing is always a scam and pretending to be the next of kin of someone dead is a pretty nasty thing to agree to.
If you have any experiences with these scams do let me know, by email.
